The ways through which the minerals form include the following order:
2. a warm solution flows through a crack in the rocks there
1. a solution forms from a liquid and dissolved substances
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
Explanation:
From the explanations above, it could be seen that a warm solution (most probably water)<em> flows through the cracks in the rocks leading to dissolution of substances to form liquid. When the liquid cools, the elements leaves and crystallize as compounds.</em>
D. The repressor is freed from the operator when lactose is present.
Think of a bacteria that comes into contact with some lactose sugar in milk. Normally it's not in milk, so the gene is repressed (prevented) from making the lac enzyme (which digests lactose). Now when it comes across some milk, it wants to make as much lac as possible to eat up all the lactose.
FYI: trp for tryptophan works the exact opposite with repressor blocking when trp IS PRESENT.
